Vinylzwerg Privacy Policy

Last updated: April 8, 2026

Vinylzwerg is a collection management app for vinyl, CDs, cassettes, books, and comics. It is designed around local storage and local control, not user profiling, identity systems, or behavioral tracking.

Core privacy position

• Vinylzwerg does not collect personal profile data about users.
• All login and registration in the app are local-only on your device.
• Media you add manually is stored only locally on your device unless you explicitly export it.
• Vinylzwerg does not implement age verification, gender collection, or person verification.
• The project does not support adding age, gender, or person verification, and if such collection ever becomes mandatory for the product direction, development would stop rather than adopt that model.
• No user data is shared with AI systems, and no AI model or autonomous agent is part of the app experience.

What stays on your device

• Your local collection data, including cabinets, cubicles, releases, tags, and notes.
• Your local username and session state for app login.
• Optional biometric unlock preference.
• Optional locally captured cover images and export files you choose to create.

Camera and biometric access

• The camera is used for barcode scanning, catalog number lookup, and cover-art capture.
• Biometric authentication is optional and uses your device operating system APIs.
• Vinylzwerg does not receive your fingerprint, face data, or device PIN.

What is not collected

• No age data.
• No gender data.
• No person verification data.
• No government ID data.
• No fingerprint or face template data.
• No advertising profile.
• No AI training data derived from your account or collection.

Limited network use for metadata lookup

Vinylzwerg does not run cloud accounts for your library, but online lookup features do send search identifiers to the Vinylzwerg backend at https://vinylzwerg.com so it can fetch metadata results and cache them.

• Search terms and identifiers such as barcode, ISBN, title, artist, or catalog number.
• Requested media type such as vinyl, CD, cassette, book, or comic.
• Basic technical request data normally generated by web requests, such as IP address and timestamps.

These lookup requests are technical request data needed to return search results. They are not used to create user profiles, ad profiles, age profiles, identity profiles, or AI training datasets.

Third-party metadata sources

The Vinylzwerg backend may query third-party metadata providers to fulfill lookup requests. Depending on the media type, this can include Discogs, MusicBrainz, and Open Library.

How backend lookup data is used

• To return search results to your app.
• To cache metadata responses in PostgreSQL and reduce repeated upstream API calls.
• To improve lookup performance and reliability for items you search.

What Vinylzwerg does not do

• It does not sell your personal data.
• It does not use your camera or biometrics in the background.
• It does not upload your fingerprint, face scan, or device passcode.
• It does not maintain a remote identity account for your app login.
• It does not share user data with any AI service.
• It does not embed generative AI, AI agents, or automated profiling systems in the app.

Data retention

• Local collection data remains on your device until you delete it or uninstall the app.
• Backend lookup cache entries may be retained for operational and performance purposes.

Policy direction

Vinylzwerg is intended to remain a local-first collection app. The project direction does not support age verification, gender collection, person verification, or AI-driven features.
